Introdução: A reabilitação oral com prótese fixa deve obedecer a um design que garanta a integridade dos dentes pilares e a própria estrutura protética. Fundamentada em conceitos biomecânicos, a lei de Ante serve como guia de orientação desse design, carecendo no entanto de evidência científica relacionada com o sucesso clínico. De forma a clarificar este conceito, propõe-se o estudo do comportamento clínico das próteses fixas aplicadas em pacientes que recorreram à clínica universitária. Objetivos: O objetivo deste estudo foi estabelecer o relacionamento entre a lei de Ante e o comportamento clínico das próteses parciais fixas dos pacientes que recorreram à clínica universitária. Materiais e Métodos: Em pacientes que recorreram à clínica universitária reabilitados com próteses fixas foi medida a lei de Ante nas radiografias através de um software que permite a determinação de áreas gráficas. Foram recolhidos também os dados clínicos relevantes sobre essa reabilitação protética. Os resultados foram processados utilizando o programa estatístico SPSS®. As principais variáveis incluídas neste estudo são a perda de retenção, a fratura das próteses, a mobilidade dos dentes pilares, a infiltração marginal e a lei de Ante. Resultados: Não existiu uma associação significativa entre a lei de Ante e a fratura das próteses, p<0.05. Não existiu uma associação significativa entre a lei de Ante e a perda de retenção, p<0,05. Houve aumento significativo da mobilidade e infiltração marginal das prótese fixas com menor cumprimento da lei de Ante, p<0,05. Conclusões: A lei de Ante foi um parâmetro importante no plano de tratamento para o sucesso clínico de uma prótese parcial fixa, uma vez que foi significativamente relacionada com a presença de mobilidade e de infiltração marginal dessas mesmas próteses. De todos os pacientes que compareceram na clínica universitária, 82,4% estavam de acordo com a lei de Ante.
Introduction: The oral rehabilitation with tooth-supported fixed partial dentures (FPDs) must follow a design that ensure integrity for the abutment teeth and the prosthetic structure. Based on biomechanical concepts, the Ante's law helps to the design conception, however there is a lack of scientific evidence. In order to clarify this concept, it is proposed the study of the clinical behavior of tooth supported FPDs of patients that attended the clinic of the Portuguese Catholic University. Objectives: The aim of this retrospective study was to establish a relationship between the Ante's law and the clinical behavior of the tooth-supported FPDs of the patients that attended the clinic of the university, in Viseu. Materials and Methods: In patients that attended the clinic of the university, rehabilitated with tooth-supported FPDs, it will be measured the Ante's law on their x-rays using a software that allows digital area measurement. It will also be collected the relevant clinical data about their prosthetic rehabilitation. The data will be processed using SPSS® statistics. The principal variables included in this study are the loss of retention, the fracture of the prosthesis, the mobility of the abutment teeth, the marginal infiltration and the Ante's law. Results: There is no significant association between Ante's law and fracture, p<0,05. There is no significant association between the Ante's law and loss of retention, p<0,05. There were significant increases in mobility and marginal infiltration of FPDs with less compliant of Ante's law, p<0,05. Conclusions: The Ante's law was an important parameter in treatment plan for the clinical success of a tooth-supported fixed partial denture, once it was significantly related with the presence of mobility and marginal infiltration of such prosthesis. From all the patients that attended the university clinic, 82,4% were according with the Ante's law.
